The optical wavelength converter can be used to increase the transmission bandwidth and transmission distance of the network. It can make the network capacity increase exponentially and quickly without affecting the original business, and greatly improve the security of the network. It has functions such as optical relay, wavelength conversion, and transmission medium conversion between single-mode fiber and multi-mode fiber. It is suitable for multiplexing transmission and wavelength conversion of various digital signals (SDH, ATM, Ethernet, Fibre Channel) and analog signals in optical fiber in the range of 10Mb / s to 2.5 Gb / s.

The short-haul transmission can be accomplished without any additional device in the CWDM system.
1, The most important advantage of CWDM system is low equipment cost.
2, Another advantage of CWDM system is that it can reduce network operating costs. Due to the small size, low power consumption, easy maintenance and convenient power supply of CWDM equipment, 220V AC power can be used. Due to its small number of wavelengths, the board backup volume is small. Using 8-wave CWDM equipment has no special requirements for optical fibers. G.652, G.653, and G.655 optical fibers can be used, and existing optical cables can be used. CWDM system can significantly increase the transmission capacity of optical fiber and improve the utilization of optical fiber resources.
3, Third advantage of CWDM System is its small size and low power consumption. CWDM system lasers do not require semiconductor refrigerators and temperature control functions, so power consumption can be significantly reduced. For example, each laser in a DWDM system consumes about 4W of power, while a CWDM laser without a cooler consumes only 0.5W of power. The simplified laser module in the CWDM system reduces the volume of the integrated optical transceiver module, and the simplified structure of the device also reduces the size of the device and saves room space.
